Help me understand people

This is purely venting.

I just bitched in chat when a guy left at his third death within 1 minute of each round, and 2 other players just took this side? Is ragequitting a god given right or what? I swear to God, it's so much more common in R6 than in any other PvP game I play that people have really got desensitized to it?

Of course, I am talking about ranked.
